COMPRESSION GREASE CUP AND CONTAINER.

Application filed March 23 To all whom it may concern:

Be it known that I, WILLIAM Pn'mn KoEPrLER, a citizen of the United States, residing at Hattiesburg, in the county of Forrest and State of Mississippi, have invented certain new and useful Improvements in Compression Grease Cups and Containers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to compression grease cups and containers adapted to be used in conjunction with the same and it consists in the novel features hereinafter described and claimed.-

An object of the invention is to provide a cup of simple and durable structure adapted to be applied to the bearing and which may remain permanently in position thereon. A grease container is used in combination with the cup for supplying the grease to the cup and the container and cup are made to cooperate with each other during the filling operation whereby the supply of grease from the container to the cup may be quickly accomplished.

In the accompanying drawing:

Figure 1 is a vertical sectional view of the cup with the container applied.

Figure 2 is a transverse sectional view of the container.

Figure 3 is a sectional view of the cap adapted to be used upon the container.

The cup 1 comprises a cylindrical body of metal which is provided with a central longitudinal bore which extends from the lower end of the body and terminates short of the upper end thereof. An orifice 3 is provided in the upper end of the body 1 and is concentrically positioned. Said orifice opens at its upper end at the top of the body and communicates at its lower end with the upper end of the bore 2. The orifice 3 is considerably less in diameter than the bore 2. The lower portion of the body is threaded as at 4 and this portion may be screwed into engagement with a bearing (not shown) in a usual manner. As the body 1 is provided at a point above the thread 4 and at its exterior with a portion 5 which may be squared, hexagonal or any other suitable Serial No. 368,048.

shape and serves the double purpose as the shoulder for the body and a portion to which a wrench may be applied for screwing the cup in position in the bearing or for removing the same therefrom.

The grease container or filler comprises a cylindrical body 6 which is rovided with a centrally positioned longituc inally disposed bore 7, said bore being smooth and adapted to snugly receive the exterior surface of the upper portion of the body 1. The bore 7 enters the body 6 from the lower end when the same is inverted and terminates short of the upper end thereof and the bore is of such length that it will permit of the lower end of the body 6 to rest on the portion 5 of the body 1 when the container is applied to the body and after the grease has been expelled from the container and forced into the body of the cup 1.

In operation the container 6 is removed from the body 1 and is filled with grease or lubricant and is then inverted and slips down over the upper cylindrical portion of the body 1 whereby the grease is forced to the aperture 3 into the bore 2 of the body 1 and may gravitate or feed therefrom to the bearing. When the grease has been applied to one cup as'hereinbefore stated the'container is removed and the operation above described is repeated in conjunction with another cup and hence it will be seen that a single container may be used for filling a series of cups. The container 6 is relatively heavy and consequently when it is applied to the cup it may be readily forced in a downward direction thereby promptly filling the cupand accomplishing the filling operation without the use of threads or other minor parts or features liable to bind or interfere with the prompt movement of the lubricant. After the container 6 has been removed from the cup 1 a tin cap 7 may be placed over the cup to prevent dust from entering the same.

Having thus described my invention, what is claimed is A two-piece grease cup having an end wall provided with a relatively small greaseentrance orifice necessitating pressure of the grease therethrough, the cup being enlarged laterally below said wall to provide a greasecontaining chamber to which said orifice leads, said. well serving as a closure for said chamber, a container of substantially cylindrical form adapted to contain a filling supply of grease, said container being closed one end and open at the other end for snug and slidable engagement on the cup, said container being operable to press the grease into the cup through said orifice, the engaging Wall of said cup and container being smooth to permit rapid application and re- 10 moval of the container.

In testimony whereof I afiix my signature in presence of two Witnesses.

WILLIAM PETER KOEPFLER.
